hi mirza,
the guy wrote the question in 2004… i’m not sure he’s still looking for the answer. But, yeah, his question was based on wrong thinking.
Regarding your answer, if you divide the bandwidth of 200kHz, it won’t give you the bandwidth of a slot. The slot is a “TIME” slot, so it is the full 200 kHz that are cut every 4.16ms.. mmm. i’m not using the right words here… nvmind 🙂
